Hi Eric

Well, there is no official statement besides the one you have quoted
below, but anyone in the Galaxy team I have spoken to recently told me
to move to PostgreSQL.

And that's why, I've been through the painful process of migrating our
MySQL database to a PostgreSQl database. Actually, the switch for our
production server just happened this morning - and I am still anxious
whether I have done everything correctly.

Our system admin also prefers MySQl. Hence I had to set up my own
PostgreSQL server. And now, I am running the back-ups myself.


For your case: why not moving the Galaxy server to the "new more
powerful environment" but still connected to the old PostgreSQL server?
I don't think the database server (unless it is sqlite) is ever the
bottleneck, is-it?


Regards, Hans-Rudolf
